摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas disposal method using an alternating combustion type hot air burner, which can reduce uncombusted components, especially, CO within exhaust gas.
SOLUTION: This exhaust gas disposal method is provided with two systems burning. A gas containing noxious components and fuel is supplied to a main burner of one system so as to pyrolyze the noxious components and recovering and a heat accumulator of the other system accumulates heat of pyrolized produced gas an accumulator of the one system recoveres and accumulates heat of the pyrolized produced gas. When the burner of the other system pyrolizes the noxious components. This exhaust gas disposal operation is repeated to accumulate the heat of the pyrolized gas produced by the burner in combustion in the heat accumulator of the burner in stoppage of combustion for use as a heat source at the next combustion. The supply of fuel to the burner in pyrolisis of the noxious components is stopped prior to the changeover of the burner when switching the burner for pyrolizing the noxious components by the changeover of a gas passage.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a hydrogen/carbon monoxide mixed gas which enables to carry out a reaction for gasifying coal and a coal layer gas safely under a pressure condition even if the coal layer gas used is rich in oxygen and furnish the mixed gas with a high hydrogen ratio without a steam reaction for reforming methane. SOLUTION: The method for producing a hydrogen/carbon monoxide mixed gas comprises supplying a carbon fuel, a coal layer gas containing mainly methane, an oxidative agent and steam to a pressure gasification unit to react, wherein the coal layer gas is previously reformed to have a reduced methane content, treated to have an increased pressure and supplied to the pressure gasifying apparatus, where the reformed coal layer gas and the carbon fuel are partially oxidized to produce carbon monoxide, a part of which is simultaneously applied to a shift reaction to convert to hydrogen.

摘要： PROBLEM TO BE SOLVED: To provide a gasification furnace designed to suppress degradation in energy efficiency by ensuring a slag tap to be kept hot without charging a quenching section with any auxiliary fuel, and also to keep a lower face of the slag tap hot with a small amount of gas to achieve a stable slag downflow, and to provide a gasification power generation plant and a gasification device.SOLUTION: A nozzle or a burner is horizontally installed at a position just below a slag tap in a quenching section, and a gas containing oxygen but containing no fuel is supplied through the nozzle or the burner to collide with a wall face of the quenching section. Alternatively, multiple nozzles or burners are made to oppose to each other and jet streams of an oxygen-containing gas supplied by the nozzles or the burners are collided with each other in the quenching section. Thereby, in the quenching section, a rising gas flow toward a lower face of the slag tap is generated. The oxygen-containing gas supplied into the quenching section is mixed with a generated gas descending from a gasification section through the slag tap near the lower face of the slag tap and burnt to keep the lower face of the slag tap hot.
